Abstract
An antenna system with co-located dipole antennas with mutually-orthogonal polarization is disclosed herein. The two antennas have planar geometry for the entire antenna and the two antennas are co-located in two mutually-orthogonal planes which provides an antenna solution for wireless communications with high isolation between the two antennas and polarization diversity in a minimum volume occupied. The two antennas operate in the same wireless communications band or in different bands.
